No worries, it's all synced up now, should be good. Let me know if any of the copy in the comments or the error message needs any massaging. Thanks! |

Instead of creating a plugin that can be also solved by a loader (which reuses webpack configuration API):
{
test: /\.jsx$/,
loader: 'abort',
query: {
message: '[resource]: .jsx extensions are not allowed, use .js extension.'
}
}

Is this an actual loader or do you propose to create one?

That's a good idea, too. @gaearon please advise.

The reasoning behind choosing loader vs. plugin:
- Loader can reuse path matching logic.
- Loader functional scope is more restrictive: you see exactly what it affects vs. plugin which can do literally anything under the hood. I'd expect the less custom plugins the better, especially when you eject and start modifying config.

Agreed. I think a loader is the more technically correct solution.

Closing now because we support JSX extension since 0.4.1 even though we don’t recommend it. Thanks for sticking with us 😄 |
Fixes#290
